CUSHION TIRE;

Application led October 18, 1926. Serial No. 142,373.

The invention aims to provide a new and improved type of cushion tire inwhich all load is jointly and resiliently carried by a resilient bodyand a plurality of spring metal rings embedded in and extendingcircumferentially oi said body.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Fig. l is a small side elevation partly broken away and in section,showing a tire constructed in accordance with my invention.

Fig. 2 is a vertical transverse section on line 2-2 of Fig. l.

In the drawings above briefly described, the numeral 3 designates anannular body of rubber or any elastic substitute either known at thepresent time or later produced. Embedded in, extending,-circumferentially of, and spaced apart over the cross section ot thebody 3, are a number ot continuous spring metal rings, said ring-s beingpreterably, although not necessarily, formed from steel. These rings andthe. body 3 are intended to jointly and resiliently carry all loadplaced upon the tire.

In the present showing. an inner, an outer, and an intermediate seriesof the spring metal rings are provided, the rings oi' said series being'given the numerals 4, 5 and 6 respectively. The rings ot each series arespaced apart about the circumferential center 7 oi the body 3, and eachseries is radially spaced from the adjacent series. These rings may beof any desired crossbectional shape, oi any desired number and size, andspaced in any appropriate manner, according to the size of the tire andthe weight to be carried.

Between the annular series of rings, the body 3 is preferably formedwith circumferentially disposed, continuous, air ducts 8 which arespaced from each other and are also spaced from the rings. In thepresent showing, additional ducts 9 are interposed between the rings 5and a main central duct l() is provided at the circumferential centeroli' the tire body. These ducts assist in i1nparting the requisiteresiliency to the body 3, and it will be understood'tbat they may be ofany desired cross-sectional size, may be spaced in numerous relations,and may be of any desirable number.

llt suitable locations, the body 3 is preterably reinforced withl'abric, cords or the like 1l, which tie all parts oitl said bodytogether and overcome any tendency toward disrup tion.

By the novel construction shown and described or a substantialequivalent, a tire is provided which will be equally as resilient as anierunatic tire, yet will be proot against the troubles incident to thepneumatic tire. The general shape, proportion and construction hereindisclosed, may be followed il desired, but it will be understood fromthe foregoing that numerous variations may be made by the manulactiuer,as occasion may demand.

lf claim :m

l. A cushion tire comprising a substan tially solid, elastic, annularbody and a plurality ot' spring` metal rings spaced apart and radiallyoutward in all directions :from the center of said body but terminatinga considerable distance from the outer surface oi the body.

2. A cushion tire comprising an annular elastic body having;l acomparatively small central annular passage, an inner central annularseries oit spring metal rings grouped. around said passage andadditional annular series olE spring metal rings spaced radially outward'trom said cent-ral tgnoup, the outer series ot rings being; spacedinwardly a considerable distance from the outer surface oi' the body.

3. lit cushion tire coinprisingil a substantially solid, elastic annularbody, and spaced series oi spring,r metal rings embedded in andextending circumterentially ot and completely around said body inconcentric relation to the center tliereoi, cach series com prising1 aplurality oi" rings, circumtercntially spaced apart, the rings of eachseries being arranged in staggered relation with the rings oit theadjacent series.

il. .A cushion tire comprising a substantially solid, elastic annularbody, and spaced series oig spring metal ringi's embedded in andenteiuliiuii circumiferentially of and comu pletely around said body inconcentric rela-- tion to the center thereof, each series com prising aplurality oi rings, circumfereln ythe rings of the adjacent series, saidbody yhaving spaced series of dead air ducts eX- tendingcircumferentially of and completely around Said body in concentricrelation to thecenter thereof and between the series of rings, the ductsof the outer series being arranged between the rings of the outer seriesof rings, and the ducts of the other series 10 being arranged oppositethe spaces between the rings of the other series of rings.

In testimony whereof I have hereunto nifxed my signature.

ADOLPHE W. SCHMIDT.
